The French Revolution: Causes, Phases and the Terror

The French Revolution is not one event, and the single biggest improvement you can make to your understanding of it is to stop treating it as one. A fiscal crisis in 1787-89, a liberal constitutional experiment, a European war from 1792, the Terror of 1793-94, and the Thermidorian reaction that followed are five distinct things with different causes, different leading figures and different supporters. The Terror was not latent in the Declaration of the Rights of Man, and the Declaration was not an inevitable consequence of a bankrupt treasury. Establishing the sequence first is what makes the causal argument tractable.

The crisis that forced the opening

The monarchy could not pay its debts and could not raise taxes without consent. That is the mechanical trigger, and it is why the Estates General — an assembly of the realm's three orders that had not met for generations — was convened at all.

The Château de Versailles dates the meeting to "4-5 May 1789" and the Tennis Court Oath, in which deputies bound themselves not to disperse until France had a constitution, to "20 June 1789". Within weeks the question had shifted from how to fund a deficit to who had the authority to answer that question.

Behind the immediate crisis sat slower pressures: a tax structure that exempted the wealthiest orders, the accumulated cost of foreign wars, poor harvests and high bread prices, and decades of political argument that had already made royal authority something to be justified rather than assumed. Keeping trigger and precondition apart is the whole discipline here. The deficit explains the timing. It does not explain why the response took the form of a constitution. The same separation is what keeps the argument over what caused the Bronze Age collapse from collapsing into a search for one villain, and it works identically in a period with far better documentation.

1789 as a documented year

The Declaration of the Rights of Man and of the Citizen was approved by the National Assembly on 26 August 1789. The Avalon Project at Yale Law School holds the text, and its opening articles are worth reading rather than paraphrasing: "Men are born and remain free and equal in rights. Social distinctions may be founded only upon the general good", and "The aim of all political association is the preservation of the natural and imprescriptible rights of man. These rights are liberty, property, security, and resistance to oppression."

In October the revolution physically relocated. The Château de Versailles records the king's departure from the palace on 6 October 1789, the moment the court ceased to be the centre of French political life. It is worth noticing what that institutional chronology foregrounds and what it leaves out: the storming of the Bastille on 14 July 1789, the event most readers name first, happened in Paris and does not appear in the palace's own list of key dates. Different institutions build different chronologies of the same year, which is exactly the phenomenon our guide to how historians date events describes.

War, and what it did to domestic politics

From 1792 France was at war with a coalition of European powers, and this is the hinge that most short accounts skip.

War changes the meaning of every domestic dispute. Opposition becomes potential treason; shortage becomes suspected hoarding; a general's defeat becomes evidence of conspiracy. It also creates the administrative machinery — requisition, emergency committees, surveillance — that emergency government then uses. Any explanation of the Terror that does not have the war in it is incomplete.

That does not make the war a sufficient explanation, and here historians genuinely divide. One tradition reads the Terror as circumstantial: invasion, civil war in the Vendée, and real conspiracies produced real emergency measures. Another reads it as ideological: a politics founded on a single indivisible general will has no legitimate category for opposition, and the machinery follows from the idea. A third focuses on institutional competition between factions in which escalation was individually rational and collectively catastrophic. The evidence supports parts of all three, and the argument has run for two centuries without resolution — which is a feature of the subject, not a failure of it.
